**What is a normal BMI and BSA?**

Another common one is the Mosteller formula, which states that BSA (m2) = SQRT( [Height(cm) x Weight(kg) ]/ 3600 ). While there are no official categories, there is an ideal BSA for men and women….

**How do you calculate BSA?**

According to Mosteller’s “simplified calculation of body-surface area In metric terms” the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.

### What should your BSA be?

The “normal” body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual. For example: Average body surface area for adult men: 1.9 m2.

**How accurate is a BMI Calculator?**

To calculate your BMI, divide your weight in pounds by your height in inches squared, then multiply the results by a conversion factor of 703. For someone who is 5 feet 5 inches tall (65 inches) and weighs 150 pounds, the calculation would look like this: [150 ÷ (65) 2] x 703 = 24.96 . An easier way is to use WebMD’s BMI calculator.

**How do you calculate a healthy BMI?**

BMI is calculated using your weight and height, so it’s an easy and inexpensive way to find out if you’re at a healthy weight. To determine your BMI, use this formula: Multiply your weight (in pounds) by 703. Divide this number by your height (in inches). Divide this number by your height (in inches), again.

#### What is ideal BMI?

For adults, an ideal BMI is between 18.5 and 24.9. A person with a BMI over 24.9 is considered overweight, and a person with a BMI under 18.5 is considered underweight. For children, an ideal number is between the 5th and 85th percentile.

**What is a normal BSA?**

The measured surface area of the body is termed as the Body Surface area or BSA in physiology and medicine. Its normal value is considered to be 1.7m². This parameter shows the metabolic mass rather than the body weight for clinical purposes. This is because the unusual body adipose mass doesn’t affect it.
